Sachs, a professor and director of the Center for Sustainable Development at Columbia University, wrote on that President Trump, Florida Senator Marco Rubio and Florida Gov. Rick Scott were “should be held accountable for climate crimes against humanity” for their “willful” climate “denial.”

“They are the authors and agents of systematic policies that deny basic human rights to their own citizens and people around the world, including the rights to life, health, and property. These politicians have blood on their hands, and the death toll continues to rise,” Sachs added.

“It is time to hold these reckless politicians to account,” Sachs demanded in his CNN commentary.

Sachs wrote at CNN that President Trump and other officials who promote climate “denial” have “blood on their hands.

In his CNN commentary, Sachs touted the UN’s climate panel as being reputable. “The Nobel-prize winning Inter-Governmental Panel on Climate Change has also just released a harrowing report showing that the world has just a few years left to move decisively towards renewable energy if it hopes to achieve the globally agreed target to limit warming below 1.5 degrees Celsius above the pre-industrial average temperature of the planet.”
